SAW-GUIDE.

SPECIFICATION forming part of LettersPatent No. 286,296, dated October 9, 1883.

Application filed April 2, 1883. i (No model.)

To all whom it may concern.-

Be it known that '1, ALLEN HAOKETT, of La Grange, in the county of Penobscot and State of Maine, have invented certain new and useful Improvements in Guides for Circular Saws; and I do hereby declare that the following is afull, clear, and exact description of the invention, that, will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming a part of this specification. in which- Figure 1 shows a top plan, Fig. 2 a bottom plan, Fig. 3 a section through line a b, Fig. 4 side view of joint; Fig. 5, plan of same.

Same letters show like parts,

My invention consists, first, of an improved guide for circular saws so constructed as to be readily adjusted and as readily taken out i of the way when the saw is to be removed from the arbor; and, second, to a special device by which the outer end of the outer lever of the 2-; when the saw is to be taken cit.

My invention will be readily understood by reference to the drawings.

At a is shown a box or casing closed at the top, within which my saw -guide is fixed. This casing is secured to the machine-frame, as common, by bolts passing through slots to allowadjustment as the saw wears away. *ithin this casing, pivoted at f f, are independentlyacting levers b 0, extending past the periphery of thesaw d, and having cavities in their, ends to receive the wooden pins 6, which come in contact with it. The under side of the casing a, is open at g g, to permit 'uide may be instantly thrown out of the way the escape of sawdust, 8220., and is provided at i the sides and through the center with shoulders or ledges h, serving as supports and guid' ing-tracks for independent plates 1 j, actuated by screws i j, operating to move them backi ward or forward at will. These plates are slotted obliquely at A Z, and into these slots pro- .furnishes a more rapid means of effecting this result by means of a joint, Z, in said outer le ver near the end next the saw, whereby said end may be raised or thrown'out to one side. I prefer that this joint shall be vertical, as in that case both the weight of the end of the lever and the action of the saw will tend to hold it in position when the guide is in use, doing away with any locking device; but if a horizont-al joint is used a spring-bolt or similar contrivance may readilybe added without the exercise of invention.

W'hat I claim as my invention is- 1. In a saw-guide, theindependently acting levers b c, pivoted atf f, with their studs m n, in combination with the obliquely-slotted plates 1' j, and adj listing-screws i j, the longitudinal movement of the said screws and plates communicating a swing movement of said levers upon their pivots, all arranged for the purposes set forth, in a suitable casing, a, substantially as described.

2. In a saw-guide, the outer lever, 0, provided with a pivoted joint, Z, near its end next the saw edge, whereby said end may be \swung out of the way when the saw is-to be changed without disconnecting iufrom its lever, substantially as and for the purposes set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 29th day of March, 1883.
